Manula is a web-based service which allows you to create professional-looking manuals and PDF guides with maximum ease and simplicity.

Manula delivers what it promises. Reliable and easy editing and maintenance of multimedia manuals that need to be published to the web or via PDF and that can be seen across any device. If I had to mention a better alternative for non-tech users, that had no download, and that was as easy to learn or adopt, I would be in difficulty in suggesting one.
